Unable to install react-native-reanimated on Expo

[Th0rgal]

Hello,

I have an existing Expo project and I wanted to install [react-native-reanimated](https://github.com/software-mansion/react-native-reanimated) because it is required by this library I would like to use: https://gorhom.github.io/react-native-bottom-sheet/

It's my first time with react-native and I enjoyed the experience so far, but after following the installation instructions and trying to run my app on ios, I got:

iOS Bundling complete 4431ms
 ERROR  Error: Failed to create a worklet. Did you forget to add Reanimated Babel plugin in babel.config.js? See installation docs at https://docs.swmansion.com/react-native-reanimated/docs/fundamentals/installation#babel-plugin., js engine: hermes
 ERROR  Invariant Violation: "main" has not been registered. This can happen if:
* Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
* A module failed to load due to an error and `AppRegistry.registerComponent` wasn't called., js engine: hermes

I couldn't run cd ios && pod install as explained on the docs as I don't have an ios folder, I guess it is not required when using expo.

Here is my babel.config.js:

module.exports = function(api) {
  api.cache(true);
  return {
    presets: ['babel-preset-expo'],
    plugins: ['react-native-reanimated/plugin'],
  };
};

Repository for Reproduction

The issue can be reproduced using my project available at: https://github.com/Th0rgal/dietgpt

Attempted Solutions

• Verified dependencies.
• Cleared caches and restarted.
• Reinstalled dependencies.

Hi! Your babel config looks correct. May I ask you which version of react-native-reanimated you installed? Libraries often aren't up-to-date on expo and you may have to use the older version than the latest one. Currently the latest supported version for expo is 3.3.0.

I cannot access the reproduction project that you linked in the description so it's hard to tell what's wrong with your setup.

I am closing it for now. If you have more questions, don't hesitate to re-open the discussion.
